Any MCP agent

VS Code and Windsurf and Zed and Goose and JetBrains and the Claude app reach the Inbox through MCP. So does any agent that speaks MCP.

MCP only · Inbox through MCP and it reads your reply when it checks

Set it up

Install Plannotator.

curl -fsSL https://plannotator.ai/install.sh | bash
Open the Inbox. It connects the agents it finds on this computer.

plannotator inbox

You should see Windsurf and the Claude app are connected if it finds them. Editors are never changed for you.
Add the Inbox to your agent as a stdio MCP server named plannotator-inbox. Settings → Agents has the exact step for your app.

plannotator inbox mcp

Use Install in VS Code in Settings → Agents, or run this.

code --add-mcp '{"name":"plannotator-inbox","type":"stdio","command":"plannotator","args":["inbox","mcp"]}'

Adds it in every project.

devin mcp add -s user plannotator-inbox -- plannotator inbox mcp

Merge it into Zed’s settings.

~/.config/zed/settings.json

{ "context_servers": { "plannotator-inbox": { "command": "plannotator", "args": ["inbox", "mcp"], "env": {} } } }

Merge it into mcpServers in Claude → Settings → Developer → Edit Config. Then quit and reopen Claude.

{ "mcpServers": { "plannotator-inbox": { "command": "plannotator", "args": ["inbox", "mcp"] } } }

Paste it in Settings → Tools → AI Assistant → Model Context Protocol (MCP) → Add.

{ "mcpServers": { "plannotator-inbox": { "command": "plannotator", "args": ["inbox", "mcp"] } } }

Use Add to Goose in Settings → Agents, or Extensions → Add custom extension → Standard IO with this command.

plannotator inbox mcp

Paste this into your agent.

Send me a test question in the Plannotator Inbox, and read my answer when I tell you I sent it.

You should see A question arrives in the Inbox. Answer it and press Send. Tell your agent you sent it and it reads your answer.

The plannotator-inbox server fails to start: An app started from the Dock may not see your shell’s PATH. Put the full path to plannotator in the config. which plannotator prints it.
claude.ai can’t reach the Inbox: claude.ai connectors can’t reach this computer. Use the Claude app.
Your agent only takes an address: Use http://127.0.0.1:<port>/mcp. Prefer the command: the port can change when the Inbox restarts.
Your reply never shows up in the session on its own: Nothing can wake an MCP agent: it sees a reply when it reads the thread. Tell it to check the Inbox.

Ask your agent to send you a guided review of its change. Comment on it in the Inbox.
